After docking, the module experienced a software glitch that caused it to accidentally fire its thrusters, causing the space station to temporarily spin and tilt.

Cosmonauts Novitskiy and Dubrov are two of seven crew members currently working on the space station.As a result of the unplanned thruster firing, the space station lost what engineers call "attitude control" for about 47 minutes, causing the orbiting laboratory to tilt from its proper orientation.
